4 Claims, No Drawings HYBRID IONIC PIIOSIPI-IORUS COMPOUNDS in which R represents hydrogen or the methyl group, I

R and R each represent hydrogen or alkyl groups of l to 4 carbon atoms and which may be identical or different, and X represents an ammonium group of the formula In the formula II, R stands for hydrogen, an alkyl or alkenyl group of l to 12 carbon atoms or a group of the formula (C,,l-I ,,O) I-I, R represents hydrogen or an aliphatic radical having 1 to carbon atoms or a radical of the formula (C,,I-I ,,O) l-I, and R represents an aliphatic radical having 1 to 20 carbon atoms or a radical of the formula (C,,l-I ,,O) H, in which n stands for 2 or 3 and the sum of all values of 2 represent 1 to 50, and the rests R and R together with the nitrogen atom may also form a piperdine, morpholine, imidazole or imidazoline ring, and preferably at least one of the radicals R, R and R means an alkyl radical or an alkenyl radical containing at least 8 carbon atoms.

The present invention further relates to a process for preparing the above-specified hybrid-ionic phosphorus compounds, wherein cyclic phosphites of the general formula Ill O-CHQ E III in which R R 'and R have the meanings given above are reacted'at elevated temperature, suitably while stirring, with primary, secondary or tertiary amines of the formula II NR R R in which R, R and R have the meanings given above.

The compounds used as starting materials are known or may be prepared according to processes known per se.

For preparing the new hybrid ionic phosphorus compounds, there may be used, as primary, secondary or tertiary amines all aliphatic amines or cycloaliphatic amines which react in the same manner as aliphatic amines.

The aliphatic radicals of these amines may be radicals having up to 20 carbon atoms and may be saturated or singly or several times olefinically unsaturated, straight chain or branched, or cyclic radicals, for example cyclohexyl. In addition to pure alkyl or alkenyl radicals, there may also be used substituted alkyl rests which contain, for example hydroxyalkyl radicals, alkylene glycol or polyalkylene glycol ether rests, aromatic rests such as the phenyl or also carbonamidoalkyl rests.

The amines of the general formula II which may be used in the process of the invention are, for example, the following amines: methylamine, isopropylamine, n-butylamine, isobutylamine, n-hexylamine, noctylamine, isononylamine, decylamine, dodecylamine, oleylamine, stearylamine, eicosylamine, benzylamine, N-methyl-N-n-butylamine, di-n-butylaminc. N- methyl-dodecylamine, N-methyLstearylamine. N- isononyl-dodecylamine, diethanolamine, dipropanolamine, di-n-octylamine, distearylamine, N- isopropyloleylamine, N-iso-propyl-di-n-butylamine, N-methyl-distearylamine, N,N-dimethyldodecylamine, N,N-dimethyl-cyclohexylamine, N,N- dimethyl-oleylamine, triisononylamine.

Suitable amines of the formula II are also the reaction products of aliphatic amines with alkylene oxides, for example the addition compounds of up to about 50 moles of ethylene oxide and/or propylene oxide and 1 mole of one of the afore-mentioned primary or secondary amines, or monoacylated alkylene-diamines, for example those of the general formula IV in which R represents an alkyl or alkenyl radical of l to 20 carbon atoms, R and R each represent hydrogen or alkyl groups of l to 3 carbon atoms, and 2 stands for 2 or 3.

ln the process of the invention, the reaction components are suitably reacted in a proportion of about 1 mole of amine to 1 mole of phosphite. In some cases, it may be of advantage to use one component, preferably the amine, with a slight excess. The reaction is preferably carried out at temperatures of about 60 to C. Depending on the boiling or melting temperature of the amine used, the reaction may be carried out in the melt or using a suitable polar solvent, for example water or alcohols, or when using low boiling amines, for example methylamine, under superatmospheric pressure. The reaction products are obtained directly with high purity, so that in general a special purification of the products is not necessary. If the reaction has been carried out in the presence of solvents, it is merely necessary to remove them by distillation.

In general, the reaction according to the invention is preferably carried out in solvents, in particular in water. Depending on the temperature used, the reaction is in most cases completed within about 1 to 3 hours. In this case, the termination of the reaction can be determined when, in view of the solubility of the reaction products in water and other polar solvents, the previously insoluble starting products have disappeared.

The new hybrid-ionic phosphorus compounds are intermediate products with versatile utility in the manufacture of, for example, pesticides or textile auxiliary agents. Compounds in which at least one of the radicals R, R or R represents an alkyl or alkenyl group having at least 8 carbon atoms, have surface-active properties. They may find versatile use as tensides. For example, they are excellent emulsifiers in the preparation of oilin-water emulsions.

Such compounds of the general formula I in which at least one of the radicals R, R or R represents an alkyl or alkenyl group containing at least 8 carbon atoms, in addition have a strong extraction power for zinc in the known processes of liquid-liquid extraction. In this respect, they are superior in their action to the known extraction agents, for example tri-n-butyl phosphate. For the liquid-liquid extraction, the aqueous zinccontaining phase is generally treated at an acid pH- value, for example at a pI-l-value of 4, with a waterinsoluble organic phase, for example liquid hydrocarbons, which contains the above-mentioned compounds of the general formula 1.

Examples of such compounds which contain aliphatic radicals with at least 8 carbon atoms are:
